Diffusion co-efficient of a metal in a solid solution depends upon its ?
Correct answer: B. Both A. & B.
- A. Composition
- B. Both A. & B.
- C. Temperature
- D. Neither A. nor B.
Explanation
Diffusion coefficient varies strongly with temperature through its exponential dependence and also changes with composition because the crystal environment and concentration affect atomic mobility. Hence both composition and temperature matter.
